Effects pedals for musical instruments like electric guitars can really expand a musician’s range with the instrument. Adding things like distortion, echo, and reverb at the push of a button …read more Continue reading An Effects Pedal for Keyboards (and Mice)
While the Fourier transform gets all the attention, there are other transforms that engineers and mathematicians use to transform signals from one form to another. Sometimes you use a transform …read more Continue reading A Quick Look at the Hilbert Transform
There’s something rewarding about building your own DIY audio hardware. Knowing you put it together yourself gives you faith in the construction, and psychosomatically makes the music sound all that …read more Continue reading A Feature-Rich Amplifier Module For 3-Way Speaker Builds
We’ve seen many DIY headphones projects on these fair pages over the years, but not many that are quite as DIY as the Ploopy Headphones. What makes this project interesting …read more Continue reading Ploopy Builds Open Source RP2040-Powered Headphones And You Can Too!
[Sebastian Holzapfel] has designed an audio frontend (eurorack-pmod) for FPGA-based audio applications, which is designed to fit into a standard Eurorack enclosure. The project, released under CERN Open-Hardware License V2, …read more Continue reading An Open Hardware Eurorack Compatible Audio FPGA Front End
[Ihsan Kehribar] points out a clever trick you can use to quickly and efficiently compute the logarithm of a 32-bit integer. The technique relies on the CLZ instruction which counts …read more Continue reading Count Leading Zeros for Efficient Logarithms
When fully-3D video games started arriving in the early 90s, some companies were more prepared for the change than others. Indeed, it would take nearly a decade of experimentation before …read more Continue reading Reverse-Engineering Forgotten Konami Arcade Hardware
If you’re one of those people who got into building electronics for the purpose of making music, then this Raspberry Pi RP2040-based audio DSP project by [DatanoiseTV] might be of …read more Continue reading A Simple RP2040-Based Audio DSP Board
The Raspberry Pi, although first intended as an inexpensive single-board computer for use in education, is now ubiquitous in electronics communities. Its low price as well as Linux platform and …read more Continue reading Processing Audio With the RP2040
Much discussion goes on in the guitar world about the best hardware to use. Whether its pickups, how they’re positioned, or even the specific breed of wood on the fretboard, …read more Continue reading Active Pickguard Makes For A Great Guitar Mod
